Product Overview

The YOKOGAWA AAI543-S50/K4A00 module functions as a specialized, high-integrity Analog Input Module, designed for use in critical Safety Instrumented Systems (SIS) or applications requiring high reliability. This essential YOKOGAWA component ensures highly accurate and dependable measurement of analog field signals, meeting stringent reliability and potential safety requirements.

Key Features:

• AAI543: Indicates the base module type, typically a 16-channel isolated analog input.

• -S50: Specifies the input signal range and characteristics (e.g., 4−20 mA or specific voltage range).

• /K4A00: Indicates a version with Safety Functionality or high-reliability coating, critical for SIS or harsh environment applications.

Detailed Technical Specifications of the AAI543−S50/K4A00

The YOKOGAWA AAI543-S50/K4A00 analog input module typically provides sixteen (16) fully isolated input channels for maximum safety and noise rejection.

Safety/High-Integrity Features and Signal Isolation

The module's design incorporates continuous diagnostics to monitor the health of the input circuit and the module itself. This high level of self-monitoring supports its use in applications requiring a high Safety Integrity Level (SIL) conformance.

The full isolation of all 16 channels ensures that faults in one field loop do not compromise the integrity of other critical signals, thus significantly enhancing system reliability.
